Problems solved by technology

[0002] In the current ship power system, there are a large number and variety of electrical equipment in local complex areas, and the requirements for power supply are also different. Some equipment requires AC power interfaces such as AC380V and AC220V, and intermediate frequency AC power supplies; Including DC power interfaces such as DC220V, DC24V, etc.; power supplies of different systems and electrical equipment cannot be directly connected. If there is no power input corresponding to the electrical system, it is necessary to select a suitable special electrical system conversion device according to the needs and characteristics of the electrical equipment. It can only be used after conversion, that is, there is an electrical system barrier problem in the multi-electrical system power supply and equipment connection of the ship
